Dual Control STI Shifters

With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear. The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts.

Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold. The drop bar STI with shift buttons located in a near identical place to the positions you'd assume shifting using a mechanical Shimano STI. Brake lever pivot is positioned to be used with super SLR brake callipers, increased power providing excellent ergonomics when riding on the hoods.

Finely tuneable reach adjusters for the levers enable custom fitment for all hands

Ultegra Rear Derailleur

With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear.

Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift. The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts.

Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts

11-32T wide gear ratio capacity will cater for compact setups as well as the traditional road double

The Di2 front derailleur's operation is pioneering, smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur. The biggest difference you will notice is just how much quicker and effortlessly smoother shifting on the front chainrings is, even under load.

The difference in the effort and time to actuate the shift between mechanical and Di2 is truly staggering. The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching, but provides effortless gear shifts.

The front derailleur also trims automatically; the cage moves in response to the position of the rear derailleur on the cassette to ensure no chain rub and a quiet unobtrusive ride, enabling you to concentrate on the road ahead.

Braze-on fit as standard; if your bike does not have a braze-on mount seat tube adapters are available

Rider-tuned means Ultegra works the way you want it. The new 11-speed cassettes are available in a range of sizes including a wide-range 11-28 option - one cassette to use all year round. Smooth, fast shifting guaranteed. The weight is 212g (11-23T).
